  • the power supply has the fault, it is possible to rescue a passenger by shorting the input of the synchronous motor by a contactor, releasing the electromagnetic brake and driving the elevator to the rescue floor at low speed.
  • Patent Document 2 proposes a method of enabling a rescue operation even when the car and the weight are balanced.
  • An emergency operation device rotates a synchronous motor for elevator operation and thus moves a car at an emergency state such as power failure.
  • the emergency operation device includes a direct current power source and a rotary switch that supplies a direct current voltage from the direct current power source to a winding of the synchronous motor and an actuator for releasing a brake.
  • the rotary switch has six contact points or contact points of the same number as the multiple of 6, and an operating interval of the contact points of the rotary switch is an angle that is obtained by dividing a total rotating angle, i.e., 360 degrees by 6 or the multiple of 6. Thereby, the direct current voltage of the direct current power is sequentially supplied to each winding.
  • the present invention has been made to solve the above-described problem.
